BATTERY MODE
The UPS automatically runs in BATTERY mode if the Mains Voltage amplitude gets out of
security limits (in case of a black-out or overvoltage-lowvoltage): in this case, the UPS supplies
the required output power by its internal battery and by the DC/DC CONVERTER, BOOSTER and
INVERTER blocks (see figure 1).
The UPS automatically returns to function in LINE mode a few seconds after the AC input line is
recovered.
The BATTERY mode is characterized by:
• An acoustic signal every 4 seconds indicates that the batteries are discharged. The acoustic
signal can be disconnected by pressing the ON/TEST/ALARM button.
• The INVERTER led and BATTERY led switched ON.
• The LOAD LEVEL and BAT. LEVEL led bars switched on.
BYPASS MODE
In BYPASS mode (see figure 1), the AC input line is directly connected with the UPS outlets by
an AUTOMATIC BYPASS.
EVO uses the BYPASS mode during the start-up phase; furthermore the UPS switches
automatically to BYPASS mode in consequence of accidental overload or Inverter fault thus
protecting the supplied devices.
The BYPASS mode is characterized by:
• The BYPASS led and LINE led switched on.
• The LOAD LEVEL and BAT. LEVEL led bars switched on.
The UPS can be transferred in BYPASS mode even through a manual operation.
First of all it must be sure that the UPS is working properly in LINE mode. On the rear side of
the product (see figure 3) it is positioned the manual BYPASS switch. If this switch is in
position ON (BYPASS), the UPS changes in BYPASS mode and indicates this condition with:
• The BYPASS led and LINE led switched on.
• All the LOAD LEVEL led bar switched on, the red OVERLOAD and FAULT Leds switched on.
• Continuous acoustic alarm.
The UPS starts working again normally if it moves the switch in OFF (NORMAL) position.
Acoustic alarm stops immediately and the UPS effectuates then an operating SELF TEST (during
which the red FAULT and OVERLOAD Leds are switched on). After some seconds more the
BYPASS led is switched off and the INVERTER led is switched on: this indicates that the UPS has
started working normally in LINE mode.
During the above mentioned operations, the devices powered by UPS will continue working
regularly
WARNING
BYPASS operations must be carried out ONLY by qualified Technical personnel
specialised and authorised by Tecnoware.
